safe_mailto problem

[eluser]Perkin5[/eluser]
I have a contact link like this:

Code:

<?php echo safe_mailto('[email protected]', 'click here'); ?>

but the words 'click me' fail to show. If I delete 'safe_', in other words make it into an ordinary link, it works fine.

With safe_mailto the obfuscated code nevertheless shows up in view source.

I have jquery running but I can't see why that would be a problem.

Can anyone shed any light on why this is happening?
